smooths out the recoil for viewing your hits! with my 24 power scopes on prairie dogs out to 450 yards the rifle barely moves. Great also for shooting for groups on paper or off-hand shooting sports like at camp perry

worth the price by D Bear, Verified Owner, October 7, 2024
This is my second KynSHOT. The first was for my 450 Bushmaster and really tamed recoil. This purchase was for a new 50 Beowulf bear gun. My concern is always controlling recoil so a follow up shot is possible.

Kynshot Review by Aaron, Verified Owner, May 28, 2023
Tried this in an overgassed 16" 450 BM suppressed. Not much difference then the 10oz rifle buffer i made with 5 tungsten weights. Swapped it to my 20" 223 with 3 wire spring and 45 gr has no recoil. 55 gr and up seams the same. Definitely softer for ...

Smooth as butter. by Nate, Verified Owner, February 2, 2023
Smooths an already buttery smooth gun out even more. Just switched from carbine to rifle buffer and this is my first introduction so take that with a grain of salt. It does it’s just very well and the price for something compatible in my experience (...

Perfect for a long barrel 5.56 build by Mike G, Verified Owner, September 2, 2025
Works like a charm, part of a larger overall solution, but at the end of the day, my rifle has very little recoil and keeps my eye on target, as well as on subsequent rounds—very high quality.

Product Info for KynSHOT AR-15 .223/5.56mm Buffer for Fixed Stock

The KynSHOT RB5001 Recoil Buffer is designed for Fixed Stock AR-15s. This is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the United States Armed Forces. This buffer has patented damping technology to absorb the shock of impact from the bolt carrier's rearward motion and to prevent bolt bounce as a new cartridge is chambered. The RB5001 reduces felt recoil 20-30%, while largely eliminating muzzle flip. The improvement in weapon accuracy - specifically second and third shot accuracy - is even more noticeable as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights.image
